Atrial fibrillation (AF) is the most common arrhythmia, affecting more than 4% of the population over the age of 60. 1,2 AF can be divided into permanent and paroxysmal atrial fibrillation (PAF). PAF is defined as at least two separate episodes of AF that terminate spontaneously in less than 7 days, usually within 24 hours. 3 These episodes of AF last greater than 30 seconds and are not related to a reversible cause.
Atrial fibrillation (AF or A-fib) is an abnormal heart rhythm characterized by rapid and irregular beating.Often it starts as brief periods of abnormal beating which become longer and possibly constant over time. Most episodes have no symptoms.trial fibrillation and a corresponding enlargement of the left atrium may cause an increase in size of the mitral valve annulus. With a sinus rhythm, the mitral annulus undergoes dynamic changes during the cardiac cycle. For example, at the end of diastole the annular area is smaller than at the end of systole.
